Hey gyuys, I am wondering how to exactly install a power switch for my computer that has blue illumination. I don't thing the power connectors themselves have a 12 volt current, do they? I'm no electrical guy and need to know for a small project i'm doing. thanks.

first what are you powering ? what are the spec's of the device? 12v + dc or 120v ~ ac

a led light would need to add a resistor for most are 3-5v DC and correct polarity

What Zero is alluding to is that a CPU power switch is a momentary switch (only passes power as long as it's held down), while those rockers are like a light switch, always on or always off. Now if you're looking to control lights or fans, you need a Single Pole Single Throw switch like the rocker switch you linked.
